GMS Field Trip
Lower Devonian Fossils in Tennessee
Saturday, May 23, 2015
The second day of the epic trip started at sunrise in front of a quarry in Tennessee. First we signed waivers, then listened carefully to all of the safety rules. After we donned our hardhats and steel-toed boots, quarry employees escorted the group into the quarry and directed us to the fossils. Immediately we were finding trilobite pygidiums (aka trilo-butts), crinoid stems, brachiopods, and plates loaded with bryozoans. I saw several crinoid calyxes and some unidentified specimens too. All around I kept hearing “Oh wow, look at this!” followed by “Oh wait, look at this!” Teresa Curl found a complete coral colony. There were so many superb fossils I think everyone came away with at least one prize piece.
